Simple design to help the nozzle from crashing into the heated bed and reduce the chances of scratches or gouges. You will have to play around and measure which size works for your personal printer since everyone has different calibration settings with the nozzle distance to the bed.
There are various sizes to help adjust for your desired height (10, 15, 20, 25, 26, 27, 28, 29, 30mm). Once printed, the object can easily be pushed onto the z-axis rod with a little bit of force.
Please message if you want a specific height that isn't provided.
25% infill
0.20mm layer height
Add a skirt at 5-10 loops and 0mm from part if having trouble with bed adhesion and not using other products to help with object adhesion.
